865Using symmetry, points B & C; and E & F are equivalent. Further simplification of the circuit leads to the equivalent resistance which is 10 ohm.

It can be seen from the above diagram that
\mathcal{R}_{eq}=\frac{20\times 20}{20+20}=10\Omega
- Akash Anand Good Work
21Further simplifications leads the circuit as below :
R(equivalent)=1/40 + 1/20 + 1/40
= 10 ohm(Ans)
i guess

86510 ohm.
- Akash Anand Excellent Job..make sure you have a correct logic/explanation for that
2290 ohm???
- Akash Anand Wrong ...try again.
- Akash Anand You tell me just one thing..resistance never can be negative..then how did you get zero???????
- Dwijaraj Paul Chowdhury IDK....how can we solve this question?
- Dwijaraj Paul Chowdhury Whats symmetry??
865Sir, if the circuit wasn't symmetrical then would star-delta transformation have been the best method?
- Akash Anand ALWAYS
150Will the resistances EF and BC be ignored?
- Akash Anand Yeah (think why??)
